Re: Two sinkung ships
If you think EMC is sinking, you don't know much about enterprise-scale storage. The Dell EMC merger is a great match overall, as EMC's hyper-converged stacks (VxRack, etc) will swap out existing servers for Dell servers and increase revenue for both companies. EMC's overall revenue may be declining a bit as things shift from big iron VMAX arrays (which are still HIGHLY relevant - but for more specific Tier 1 workloads) to converged, hyper-converged and all-flash arrays.
VSAN and ScaleIO are still gaining traction as they're starting to be seen more and more outside of non-prod and tier-2 apps, and moving into larger scale tier 1 workloads. That shift is a natural course and EMC is adjusting as revenue shifts from it's mainstay (VMAX) to things like XtremIO - which is growing quite a bit.
The unknown I think is where VMware sits in all of this, does it stay put or spin-off as a separate company, who knows at this point. Overall though, EMC/Dell is poised to create a powerhouse that has an incredibly strong portfolio across pretty much every use case. And no, I don't work for Dell or EMC. :)
